well, we know that 1ft³ = 7.48 gallons, alright, we have a volume in gallons and a diameter in feet, so if we were to use the diameter in feet to get the volume what we would end up will be a volume in ft³, so let's convert firstly the gallons to ft³ then
why do I use a fraction? for the sake of not losing value in the rounding, so let's use the fraction for the volume of a right-circular cylinder
Answer:
The area of the shaded region is: 32.25m^2
Step-by-step explanation:
Given
See attachment for rectangle and semicircles
Required
The shaded region
We have:
--- length of the rectangle
This means that the diameters of the three circles add up to 30m.
So, the diameter of 1 is:
The area of one circle is:
The area of the three circles is:
The area of the rectangle is:
Where r is the radius of the circle
And
So, we have:
So, the shaded region is:
